' shoes, and to an improved method of making or treating thesame. s

A is well understood by those ,familiar with the subject, chrome-leather inits natural state is not suitable for use as soles'in' the manufacture of boots and shoes, owing to the fact that this class of leather is naturally soft and loose in fiber, and does not 'therefore have sufficient firmness or body,

or possess proper wearing qualities to war-- the purpose stated, and fur-' rant its use for thermore in its natural'state it is most difiicult, if not imposslble to properly edge the same.

The present invention relates to a leather produced from chrome-leather in such manner as to produce I ness and wearing qualities to. oak-tanned sole leather, and which when used as a sole may readily be edged-and one that will be substantially waterproof. Y

According to the present invention I treat chrome leather, or the soles cut therefrom, with acompound or composition consisting 'of a resin dissolved in, asuitable hydrocar bon solvent, such for instance as naphtha, benzin, or'benzol, the latter being preferable,

a suitable proportion of any of the known nondrying oils, such as parafiin oil, being added if necessary ness and pliability to the finished product.

' I may employ resin in any example as resin or rosin. When IOISIHJS employed it is first ground to a powder and then thoroughly-dissolved 'in t he solvent,

' An inexpensive and rapid method of treating chrome leather soles according to this invention consists in first cutting out the soles from elm-0111 l ath r, illen placing a number of them 111 at wlrej basket and-11nlnersing the same in a tank containing the compound, allowing the basket with the soles therein to remain in the compound for a period vilrying from five seconds to two minutes, depending upon the thickness of the soles. The basket is then Withdrawn from the tank, the soles taken out, end dried in any suitable Way.

The chief advantages resulting from treating chronic leather soles according to the present invention, reside in the cheapness of the compound, the simplicity of the method,

and the great saving in time and labor over the usual. methods of treating leather.

What I claim is 1. As :1 new article of manufacture, a sole.

2. A compound for treating leather nm1ntuining a liquid state at ordinary temperatures and consisting of substantially five parts of resin, five parts of naphtha, and one part of pcrafiin oil.
